A fixing means for fixing a screen panel on a support structure includes an insert member adapted to fit into a bore formed on the underside of a corner of a screen panel. The insert member has a first upper curved surface forming the major part of the insert member and having a uniform curvature of substantially more than a semi-circle, a second intermediate cylindrical grooved portion that is contiguous with the lowermost end of the first curved portion and is considerably smaller in cross-section compared to the upper curved portion, a third lower straight cylindrical surface which is a straight cylindrical portion contiguous with the second groove portion and is smaller in cross-section compared to the major top curved first portion, and a fourth straight substantially horizontal surface. The insert member has an inner vertical bore of suitable dimension to accommodate a holding means such as a bolt, a screw, or other equivalent to fixedly hold the insert onto a panel support member.
